According to the latest data from IDC, four of the top five worldwide vendors eyed shipment increases year-over-year and solid growth in Q2 2012.

Global tablet shipments hit 25 million units, with a 66.2-percent year-over-year increase, while Apple’s iPad set a shipment record in Q2 2012 by jumping from 11.8 million units shipped in Q1 2012 to 17 million.

Samsung sits at second place with 2.4 million units shipped, which is an increase from 1.1 million units in Q2 2011, and ASUS notably almost tripled its amount of units shipped from a year ago. Interestingly, shipments of the Google/ASUS-branded Nexus 7 are not a part of these totals.
